Copper beneficiation equipment/copper ore beneficiation equipment/copper ore beneficiation method technical information copper ore includes copper carbonate ore and copper oxide What are the beneficiation methods for ores and copper ores? Copper beneficiation equipment/copper ore beneficiation equipment/copper ore beneficiation methods are introduced to you as follows:
(1) Copper carbonate ore
Precipitated carbonic acid Among copper ores, the main copper minerals are rhodochrite, rhodochrosite, manganese-containing calcite and rhodochrosite gangue. Silicate and carbonate minerals are often accompanied by impurities such as sulfur and iron. Some sedimentary sulfur-containing copper carbonate ores and some hydrothermal lead-zinc copper carbonate ores adopt a flotation-strong magnetic separation process. There is little practice in the beneficiation and production of copper carbonate ore, and strong magnetic separation, heavy medium copper beneficiation equipment/copper ore beneficiation equipment/copper ore beneficiation methods and flotation methods have been studied. Both manganese oxide and copper carbonate ores contain some refractory ores. Manganese is closely symbiotic with iron, phosphorus or gangue. The embedded particles are extremely fine and difficult to sort. Therefore, smelting methods can be considered. Ore is generally complex, with copper minerals embedded in particles as fine as a few microns and difficult to dissociate, making it often difficult to obtain higher concentrate grades. Some carbonate-rich copper ores also use roasting methods to remove volatile components and obtain finished ores.
(2) Copper oxide ore
The main beneficiation method for copper oxide ore is gravity separation. Iron and manganese are difficult to separate by gravity separation, flotation or strong magnetic separation, so reduction roasting magnetic separation method is required. Some sedimentary primary copper oxide ores are depleted due to mining, so heavy media and jigging gravity separation are used in production to remove gangue and obtain massive concentrates. The raw ore is washed to remove the sludge, and some of the resulting clean ore can be used as finished ore, while some need to be re-selected using jigs and shakers. Weathered copper oxide ore often contains a large amount of slime and fine ore, and is produced using a washing and separation method. Mainly secondary copper oxide ores from weathered deposits, as well as primary and secondary copper oxide ores from some sedimentary and hydrothermal deposits. Among iron-containing copper oxide ores, the iron mineral is mainly limonite. Ore washing overflow sometimes needs to be further recovered by methods such as gravity separation or strong magnetic separation. The copper minerals in the ore are mainly hard copper minerals, soft copper minerals and hydrocopper minerals. The gangues are mainly silicate minerals. There are also carbonate minerals often accompanied by iron, phosphorus, nickel, cobalt and other components. The industry has adopted the process of ore washing, reduction roasting, magnetic separation and gravity separation.
